I was trying to make my setup here as close to your code to try and see the problem. Would you say that the linux-stable tree at 3.4.9 has the same tg3 code as your distro? I'm not able to see a problem with 3.4.9 at gigabit or 100mbit on my setup here. >> 2.

Probably stupid question but have you have tried a different cable? You mentioned that the switch side works with a laptop? What is the link speed on the laptop at that time? > >> 7.
